- The inherent safety and performance properties
of Envirotemp® FR3TM fluid have led to its application in
electrical equipment other than transformers, including
industrial electromagnets, klystron modulators,
transformer/rectifier sets, power supplies for luminars,
and heat transfer applications for testing equipment.
- Envirotemp FR3 fluid has excellent lubricity, an important
characteristic for application in equipment with
movable parts. High voltage oil impregnated paper,
cable, and bushing application also appear very
promising due to the fluid’s excellent ability to minimize
insulating paper degradation and its desirable
gassing tendency value of -79 µL/min.
- The suitability of each application of Envirotemp
FR3 fluid is the responsibility of the user. Contact
Cooper's Dielectric Fluids Products at 800-643-4335 for application guidelines.
Note:
Occasional headspace exposure to air can
occur, such as the operation of pressure relief
devices, temporary hand-hole cover removal,
etc. without detectable degradation of the
fluid properties. However, minimal air exposure
is preferred as the fluid is more susceptible to
oxidation than petroleum-based products.
Applications with continuous free breathing
equipment is not recommended.
